I was looking at the specs for these drives.

The samsung is 9.7ms seek time the 640 black is 11.7.

This has the new SATA II 6.0Gbs , Samsung is 3GB. For now I support 3GB but in the feature its nice to have that .

average latency both were about same 4.2ms

I dont need more then 500GB actually soo dont take size into consideration. Which one is the faster drive and how much will the 64MB cache help the 640GB black. Thanks all Sorry if this seems like a double post..Thanks
 
You can't have SATA III unless your motherboard supports it, and unless you just bought or upgraded the motherboard in your system it won't. It will run at SATA II speeds either way. Go with the Samsung.
 
Well as I said Ill be using 3.0sata Im said in my message I wouldnt mind 6.0 for someday in the future. its good feature to have.. also the 64mb cache,

so the samsung is faster uh david

Apparantly nobody told you that drives don't get faster with time? It's a completely useless feature to have for any current HDD. Also the 64mb cache are only useful in some few benchmarks.

The Spinpoint should be faster in benchmarks, but that'll be hardly noticeable in any real application
 
Cache hardly has any association with speed. It's like how computer manufactures advertise computers have 4GB ram, obviously it does, but does 4GB ram and a celeron processor really better than an i7 with 3GB ram...? that's a no.
 
SATA II or SATA III makes absolutely no difference whatsoever to these drives. Neither can possibly hope to saturate SATA II transfer speeds.

Straitening a corner on a highway makes sense if you intend to drive a car on the highway, but for a bicycle, the extra speed potential of the improved highway won't make a difference. HDDs are bicycles.

According to this site, the WD 640 drives come with 2 or 3 platters. Model WD6401AALS-00J7B1 has 3 250Gb disks, and the WD6401AALS-00L3B2/003B20/00E8B0 models have 2 320Gb platters. I haven't seen anyplace that shows a single platter WD 640 drive.

The same site says the Samsung F3 comes with a single 500Gb disk for all the drives between 160 and 500Gb, and 2 500Gb plates for the 750 and 1Tb drives.

It looks like the biggest HDD you can get that sports a single platter is 500Gb, and all the major players have at least one.
